Cité des sciences – Main Entrance – Outdoor Parvis Nord

Car hacking (June 30th – 11:00 / 18:00 and July 1st, 11:00 / 19:00all day)

@RatZillaS will animate a permanent workshop in the outdoor space of the Cité des Sciences ! These practical workshops will focus on the radio, electronic, and software aspects of the demonstration vehicle (By all accounts a cute Japanese one ;).

In 2022 there were 133,800 car thefts, either one car stolen every 4 minutes

The theft of hybrid or electric vehicles has increased by 70%, which proves the need to think about the safety of vehicles from their design. The connectivity of these vehicles brings comfort but also new cyber vulnerabilities. These workshops aim to shed light on the state of the threat but also parades to ensure the protection of property, people in and around these vehicles
